New Type of Bacteria Reportedly Found in Buried Antarctic Lake
2013-03-08 00:52:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: A new type of microbe has been found at a lake buried under Antarctica's thick ice, according to news reports. The find may unveil clues of the surrounding environment in the lake, according to scientists. The bacteria, said to be only 86 percent similar to other types known to exist on Earth, was discovered in a water sample taken from Lake Vostok, which sits under more than 2 miles (3 kilometers) of Antarctic ice. The freshwater lake has likely been buried, unaltered, under the ice for the past...
Past Antarctic warming linked to greenhouse gas
2013-02-28 21:00:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: Rising carbon dioxide levels may have caused Antarctic warming in the past, new research strongly suggests. The findings, published today (Feb. 28) in the journal Science, just add to the body of evidence that human-caused greenhouse gas emissions will lead to climate change. "It's new evidence from the past of the strong role of CO2 [carbon dioxide] in climate variation," said study co-author Frédéric Parrenin, a climate scientist at the CNRS in France. Past data Eons of the Earth's climate...
New Source Found For Cold, Deep Antarctic Currents
2013-02-24 11:12:00| Climate Ark Climate Change & Global Warming Newsfeed
LiveScience: With help from seals, scientists have discovered a new source for the coldest, deepest water in the ocean. Instruments glued to seals' heads tracked Antarctic Bottom Water flowing down deep canyons off Cape Darnley in East Antarctica. The spot was an unexpected font of the bottom water -- cold, dense, salty water -- because it lacks the broad underwater shelf of the unique current's three known sources. These shallow shelves stick out from the continent's edge. Cold water flows over the edge to...
